dc7680e859 net/netvsc: support integrated VF
Integrate accelerated networking support into netvsc PMD.
This allows netvsc to manage VF without using failsafe or vdev_netvsc.
For the exception vswitch path some tests like transmit
get a 22% increase in packets/sec.
For the VF path, the code is slightly shorter but has no
real change in performance.

Pro:
   * using netvsc is more like other DPDK NIC's
   * the exception packet uses less CPU
   * much smaller code size
   * no locking required on VF transmit/receive path
   * no legacy Linux network device to get mangled by userspace
   * much simpler (1K vs 9K) LOC
   * unified extended statistics

Con:
   * using netvsc has more complex startup model
   * no bifurcated driver support
   * no flow support (since host does not have flow API).
   * no tunnel offload support
   * no receive interrupt support

323e7b667f ethdev: make default behavior CRC strip on Rx
Removed DEV_RX_OFFLOAD_CRC_STRIP offload flag.
Without any specific Rx offload flag, default behavior by PMDs is to
strip CRC.

PMDs that support keeping CRC should advertise DEV_RX_OFFLOAD_KEEP_CRC
Rx offload capability.

Applications that require keeping CRC should check PMD capability first
and if it is supported can enable this feature by setting
DEV_RX_OFFLOAD_KEEP_CRC in Rx offload flag in rte_eth_dev_configure()

1e5e3d2e72 ethdev: fix MAC changes when live change not supported
Current code assumes a MAC change can occur when the port has been
started. In fact, there are some NICs which require this port state
for being successful, but other NICs not always support MAC change
in that case.

This patch supports a new device flag for a device advertising this
limitation, and if the flag is set, the MAC is changed before the
port starts.

f9de87187b net/mlx5: disable ConnectX-4 Lx Multi Packet Send by default
On ConnectX-4 Lx the Multi Packet Send (MPW) feature is considered
un-secure, as on some cases were the application provides incorrect mbufs
on the Tx burst the host or NIC can get stuck.

Hence, disabling the feature by default for this specific NIC.
Users can still enable this feature and enjoy the performance gain
(mostly for low number of cores) by using the txq_mpw_en devarg.

This patch will impact the out of the box performance of some application
using ConnectX-4 Lx for the sack of security and robustness.

Since we need different defaults based on the underlying device the mpw
field in the configuration struct was extended to contain also the
MLX5_ARG_UNSET option.

The patch changes rx_burst profiling approach:

	2. empty hook callback for profiling is added
This way all VTune-specific logic moves to the VTune side.
Hook is enabled only when CONFIG_RTE_ETHDEV_PROFILE_WITH_VTUNE option
is turned on. VTune uses this hook to attach to the polling cycle. It
is not possible to attach to the rx_burst directly, as it is inline.
